The correct order of the process that occurs when a sperm encounters an egg is the Osperm reaches ovum, implantation occurs, zygote is formed, embryo begins secreting hCG. sperm reaches ovum, zygote is formed, implantation occurs, embryo begins secreting hCG. sperm reaches ovum, embryo begins secreting hCG, implantation occurs, zygote is formed. sperm reaches ovum, embryo begins secreting hCG, zygote is formed, implantation occurs.

Match the asexual reproductive strategy to its definition fission gemmulation budding fragmentation parthenogenesis [Choose ] [Choose ] both reproductive systems can be found in the same organism enhances reproductive success by encouraging genetic diversity the organism breaks into one or more pieces uses unequal mitosis relies on mitosis to produce "daughter cells" the female transforms herself into a male cells are surrounded by a resistant capsule no sperm required for progeny to be made [Choose ] [Choose ] <

What is a dauer larva ? It's a larva from a special variant of C. elegans that was first identified in samples from soil in Germany It is a larva that shows accelerated development in highly nutritious environments Dauer is just the technical term for "hermaphrodite" - so dauer larva means hermaphrodite adult It's a larva that arrests development in a low metabolic and enduring stage, caused by harsh environmental conditions. The larva will remain in the dauer stage until the conditions improve, at which point they'll resume development.
